Products for civil engineering and road and railway construction were a passion of the company's founder, Leo Bermüller, as far back as 1960. In the course of the company's history, we have developed from a regional trading company to a pan-European specialist in modern construction products. Today, the company is run by Rudolf Bermüller, representing the second generation of Bermüllers and, with Stefan Bermüller, the next generation is already waiting in the wings to lead the company to further success in the future.

We offer a comprehensive range of geotextiles, such as non-woven fabrics and woven geotextiles, geotextile-related products such as geogrids, asphalt reinforcement grids, drainage mats, drainage grids, erosion control mats, geosynthetic clay liners, also known as bentonite mats, and sealing membranes, all of which belong to the category of geosynthetics.

BEGRID TG Geogrid

Bildunterschrift Beschreibung

The mode of action of the BEGRID TG Geogrid is simple and effective. Loads within the structure are distributed across a wide area by the geogrid before being transferred to the subsoil, thus avoiding any overloading caused by point loads. This avoids the need for costly and laborious earthworks, such as soil improvement measures or the replacement of soil with load-bearing material.

BEGRID TG Geogrids produce excellent results in terms of reinforcement. BEGRID TG is made from UV-resistant polypropylene (PP) membranes. In the production process, a predefined pattern of holes is punched into the membranes, which are then stretched laterally and longitudinally. This forms a dimensionally stable geogrid with low elongation.

The extremely robust and bending-resistant grid structures consist of monolithic ribs and intersection points. In contrast to other types of geogrid, no jointed nodes are formed during production. The geogrids are instead formed from a single piece of material. These typical product characteristics make BEGRID TG particularly well suited for use in civil engineering and road construction.

TERRAMESH Green

Design of TERRAMESH Green

The areas of application cover a broad spectrum, from traditional subgrade stabilisation through to noise barriers, embankments and wall structures.

One area that presents a special challenge with regard to slope stabilisation is the construction of extremely steep embankments and wall structures. The reinforcement must be designed to provide the structure with adequate stability, to ensure internal and external stability against collapse and to protect the exposed surface against erosion.

In the meantime, infrastructure elements also have to fulfil increasing expectations regarding their appearance and ecological compatibility, whilst also being financially viable. TERRAMESH system solutions, made of innovative steel wire elements, offer a reliable and economic alternative to traditional construction methods using concrete.

BEVENT SK Structured Separating Layer

BEVENT SK is a bond of a a three-layer vapour-permeable separating roof underlay membrane and a randomly arranged monofilament wire mat. The product is equipped with a self-adhesive butyl stripe.

BEVENT SK serves as a ventilation and spacer layer between the roof structure and the metal cladding. The open structure of the randomly arranged monofilament prevents the permanent accumulation of water, and the vapour-permeable roof underlay membrane provides the highest level of protection against the elements during the construction phase.

If you wish to protect insulation layers, flat-roof sealing membranes or waterproofing membranes of buildings against mechanical damage, then structural protection mats made of granulated rubber are the ideal product. These mats can also be used as a temporary protection layer for floors or stairs.

REGUM structural protection is available as mats or sheeting and can be laid quickly and easily. The material is permeable to water, weather-resistant, absolutely rotproof, and is able to support loads immediately after unrolling and laying.

Safety surfaces made of granulated rubber enable you to meet playground safety standards. They can also be used to excellent effect in outdoor areas in retirement homes, care centres, hospitals, leisure parks, swimming pools, shopping centres, hotels and gardens.

A cost-effective green sports field that requires no mowing, fertilising or watering, and can be used the whole year round, whatever the weather, is the dream of every lawn sports enthusiast and all investors.

This dream finally became reality in the mid 1970s and is the reason for the subsequent worldwide success of synthetic turf. Over the years, different types of synthetic turf have been developed and constantly improved.

BETEX TP Non-woven Fabrics

Geosynthetics

General information about BETEX TP Non-woven Fabrics

General information

The range of applications for non-woven geotextiles in civil engineering is as wide as the range of structures in which they are used. Non-woven fabrics are the archetypal geosynthetic. Depending on the structure and composition of the fabric, they can be used as a filtering, separation or protection layer in highway construction, buildings, civil engineering, gardens and landscaping.

The mode of operation is always similar, but the requirements of different construction projects can vary considerably.

BETEX TP is a mechanically-bonded staple fibre geotextile made of polypropylene (PP). This polymer demonstrates high chemical resistance, even to aggressive media such as soils with a high pH value. The geotextile is easy to handle and lay. As a result of its high elasticity it is also extremely flexible without any associated loss in robustness.

BETEX TP fabrics can thus be used to clad even complex shapes to excellent effect. The exceptionally wide range of BETEX TP Non-woven Fabrics allows them to be used in practically all types of application.

Functionality of BETEX TP Non-woven Fabrics

Functions

Separation

BETEX TP Non-woven Fabrics can be used to separate two different types of soil or unbound sub-base layers from each other. This separating function is extremely important, for example in cases where the subgrade soil must be prevented from mixing with a high-quality sub-base layer.

By separating the layers, the quality of the layer structure can be sustained in the long-term and the useful life of the structure can be optimised. The separating function of the fabric often means that a blinding layer can be omitted.

Bildunterschrift Beschreibung

Filtration

The filter function of the non-woven fabric must be tailored to the particular circumstances, depending on the grain mobility within the soil and the influence of water on the layers to be separated. In simple cases, such as those assumed in M Geok E StB 2005 (Leaflet on the use of geosynthetics in earthworks for highway construction), BETEX TP Non-woven Fabrics provide the necessary mechanical and hydraulic filtration.

For more complex applications, the ideal product can be selected from the BETEX TP product range after determining the filter requirements and taking into account the characteristic aperture width, the water permeability and possibly also the filtration length.

In general, the functions of separation and filtration complement each other, and this dual function is often a prerequisite in geotechnical applications.

Bildunterschrift Beschreibung

Protection

The protective function of the fabric can be considered in isolation from the two functions described above. In this case, the purpose is to protect a structure or another functional component, such as a sealing membrane, from mechanical damage. Such protection may be required, for example, when concreting or positioning large-grain mineral construction materials.

Here BETEX TP Non-woven Fabrics provide the necessary protection. They can minimise the effects of point loads and absorb shear forces. Our BETEX TP Non-woven Fabrics are available in various weights to provide the required level of protection for an extremely wide range of applications.

Areas of application about BETEX TP Non-woven Fabrics

Applications

BETEX TP Non-woven Fabrics are used as separating and filtering layers in situations where soil and mineral fill materials need to be effectively separated in order to prevent the migration of particles and the formation of unstable interfaces.

Non-woven fabrics belong to a category of construction materials that can influence the function of structural elements and even affect the stability of entire structures. Special applications in civil engineering require some form of differentiation in order to ensure that the right non-woven fabric is selected. ... To the product
